(Taeniamia fucata), also known as the Pygmy Cardinalfish, is a small marine fish species belonging to the family Apogonidae. It is a common species found throughout the tropical waters of the Indo-Pacific region, including the Red Sea, Indonesia, Australia, and the Pacific Islands.

The Dotted Cardinalfish is a relatively small fish, growing up to 5 cm in length. It has an elongated body shape with a narrow head and a pointed snout. The dorsal fin is tall and extends almost the entire length of the body, while the anal fin is much shorter. The caudal fin is forked and rounded at the tip, and the pectoral fins are large and rounded.

The body of the Dotted Cardinalfish is mainly yellow to light brown in color, with distinctive black dots on the upper half of its body and fins. The lower half of its body is lighter in color, with a white or light yellow hue. The overall body coloration helps to camouflage the fish among the rocks and coral reef where it lives.

Dotted Cardinalfish are typically found in small groups and are primarily nocturnal feeders, preying on small invertebrates and plankton. During the day, they tend to hide among the rocks and coral, but at night they venture out to feed. They have a peaceful nature and are often kept in home aquariums, although they require a well-established reef environment with plenty of hiding places.

In terms of fashion, the Dotted Cardinalfish has a unique appearance with its distinctive spotted pattern. This makes it a popular choice for aquarium enthusiasts looking to add a splash of color and interest to their reef tanks. However, it should be noted that while they are relatively easy to care for, they are also quite delicate and require specific water conditions to thrive.

In summary, the Dotted Cardinalfish is a small but fascinating marine species found throughout the tropical waters of the Indo-Pacific. Its elongated body shape, yellow to light brown coloration with black dots, and nocturnal feeding habits make it a unique and interesting addition to any aquarium.
